To simplify the expression \((-24/7) \times (-14/9)\), we can follow these steps:
### Step 1: Multiply the numerators and the denominators
We start by multiplying the two fractions directly. The product of two negative numbers is positive.
\[
(-24/7) \times (-14/9) = \frac{(-24) \times (-14)}{7 \times 9}
\]
### Step 2: Calculate the product of the numerators
Now we calculate the product of the numerators:
\[
(-24) \times (-14) = 24 \times 14
\]
Calculating \(24 \times 14\):
\[
24 \times 14 = 336
\]
### Step 3: Calculate the product of the denominators
Next, we calculate the product of the denominators:
\[
7 \times 9 = 63
\]
### Step 4: Write the fraction
Now we can write the fraction with the calculated numerator and denominator:
\[
\frac{336}{63}
\]
### Step 5: Simplify the fraction
To simplify \(\frac{336}{63}\), we need to find the greatest common divisor (GCD) of 336 and 63.
First, we can divide both numbers by 9:
\[
336 \div 9 = 37.33 \quad \text{(not an integer)}
\]
\[
63 \div 9 = 7
\]
Next, we can check for 3:
\[
336 \div 3 = 112
\]
\[
63 \div 3 = 21
\]
Now we have:
\[
\frac{336 \div 3}{63 \div 3} = \frac{112}{21}
\]
Now, we can simplify \(\frac{112}{21}\) further. We can check for 7:
\[
112 \div 7 = 16
\]
\[
21 \div 7 = 3
\]
So we have:
\[
\frac{112 \div 7}{21 \div 7} = \frac{16}{3}
\]
### Final Answer
Thus, the simplified form of \((-24/7) \times (-14/9)\) is:
\[
\frac{16}{3}
\]
